St. Petersburg, Florida — Receiving a letter alerting you to a potential data breach can be unsettling. Joan E., a viewer from Largo, recently received such a letter regarding her Medicare plan, prompting concerns about the safety of her personal information.

The letter informed Joan that her data may have been compromised in a cyberattack on Greylock McKinnon Associates Inc. (GMA), a firm contracted by the U.S. Department of Justice. The breach potentially exposed sensitive details like names, birth dates, addresses, Medicare Health Insurance Claim Numbers (which include social security numbers), and other medical/health insurance information.

Verifying the Breach

Joan’s skepticism led her to seek verification from reliable sources. The VERIFY team, along with input from various experts including Kylie Mason from the Office of the Maine Attorney General, confirmed the authenticity of the breach.

GMA officially began notifying affected individuals on April 5, 2024. The investigation revealed that 341,650 Americans, including Joan, were impacted by the cyberattack on May 30, 2023.

Clarifications and Reactions

While GMA clarified that the breached information wasn’t directly related to ongoing litigation, they offered affected individuals two years of free credit monitoring as a precautionary measure.

Erich Kron, a security awareness advocate at KnowBe4, emphasized the importance of remaining vigilant, suggesting that the impact of such breaches can extend far beyond the initial incident.

Delays and Legal Recourse

John E., another viewer from Zephyrhills, expressed concerns about the delay in notification, wondering why it took nearly a year for affected individuals to be informed. State regulations dictate the timeline for breach notifications, with Florida law requiring notification within 30 days if at least 500 Floridians are affected.

However, GMA’s delay in notifying consumers raised questions. Despite detecting suspicious activity in May 2023, affected individuals were only notified in April 2024. This delay underscores the challenges in timely breach detection and notification.

Protecting Yourself

In light of such incidents, individuals are urged to take proactive steps to safeguard their information. Kron advises vigilance, especially when sharing data with unfamiliar third-party organizations. Recognizing phishing attempts and avoiding password reuse are crucial steps in mitigating risks associated with data breaches.

Conclusion: Prioritizing Vigilance and Prevention

The GMA data breach serves as a sobering reminder of the constant threat posed by cyberattacks. While legal recourse and government interventions play a role, individual vigilance and proactive security measures remain paramount in protecting personal information from exploitation and fraud.
